SYLVESTER MANOR EDUCATIONAL FARM’S
CLEAN WATER SYSTEM
Sylvester Manor broke ground in September 2016 and expects to complete construction before winter on the first-of-its-kind in Suffolk County non-proprietary constructed wetland treatment system. The full system title is “Non-Proprietary Vegetated Gravel Recirculating Constructed Wetland Alternative Onsite Wastewater Treatment System.” The system will process effluent from new, temporary kitchen and restroom facilities. These facilities will provide ADA-compliant restrooms for Manor program participants and visitors, and bathrooms, showers, laundry and kitchen facilities for Sylvester Manor resident apprentice and WWOOFer farmers who reside at the Manor each year from April through October.
The technology has proven effective in reducing sanitary system wastewater nitrogen by up to 90%, or more, in other regions of the U.S., and was engineered by Natural Systems Utilities Engineering (NSU), which has designed and installed more than 80 such systems. As the first in Suffolk County, it will be studied along with other like projects for full regulatory approval and replicability; and the pilot system requires a conventional sanitary system as back up. The Manor’s system is being constructed and installed by NSU in partnership with Shelter Island Sand & Gravel, a local excavating firm, bringing the new technology and economic development opportunities into the local community.
